It's important to keep track of the scale of the damage. At typical velocities, one destroys about 1.7oz of tissue, the other about 1.1oz of tissue. It becomes very clear how important it is to put the bullet in the right place. Destroying an extra half ounce of non-essential tissue won't make any practical difference at all.
That is only if the full caliber width is damaged, the FMJ notoriously does little damage as it slips through, hence the deep penetration.
This thread is a waste of good bandwidth.
